AI Technical Summary
During the use of existing freight elevators, if staff fail to pay attention to the location of the items when pushing items into the freight elevator car, it is easy to cause the left and right sides of the freight elevator car to impact the side walls of the freight elevator shaft, causing long-term damage and increased maintenance problems.
A freight elevator with a buffer structure is designed, including cushion pads, fixed sleeves, buffer blocks, buffer springs, slide frames, buffer plates, rotating rods and sliding rods on the inner side of the freight elevator car and on the left and right sides of the car. Through the mutual cooperation of these components, the impact force is absorbed by the shrinking effect of the buffer roller, the buffer plate and the buffer spring, and the impact force of the freight elevator car and the elevator shaft is reduced.
It effectively reduces the impact force of the freight elevator car and the side walls of the elevator shaft, extends the service life of the equipment, reduces the number of maintenance times, and improves the safety of use.

[0003] In the related art, a freight elevator car is a box-shaped space used by elevators to carry and transport personnel and materials. Application number: CN 217732354 U discloses a traction freight elevator with an anti-collision buffer structure. In this scheme, the suction cup at the bottom of the freight elevator car hits the buffer plate.

At the same time, the buffer elastic part at the bottom of the buffer plate contracts and buffers, which can minimize damage and is safer to use. However, when the device is in use, the staff will use tools to push items into the freight elevator car. During the pushing process, if the staff does not pay attention to the position of the items in the freight elevator car, the left and right sides of the freight elevator car will hit the side walls of the freight elevator shaft under the impact of the items.
